The question of measuring ROI of social computing is hot because it's so much a part of enterprise software acquisition. As information and knowledge management professionals move to get ahead of this emerging technology curve, they find a very consistent pattern:
People are using this stuff! Blogs and wikis in particular are popping up everywhere. Why not? They are easy to access, often free, and they are dead simple to use. It's one of those permission / forgiveness things. We've all done it.
If people are using these things that IT doesn't know about, there is no way of ensuring security, privacy, availability, governance, compliance, risk mitigation and all of those good things that keep the organization running and employees out of trouble (maybe even jail!).
Most really don't want to shut it down because in many instances these are more efficient solutions than those provided by the organization. These tools are often just easier and better for generating and publishing content.
The natural inclination in this situation would be to bring in the tradtional software vendors and see if they can support these new technology directions. Not surprisingly, a number of big vendors are ready and willing to help, including BEA, IBM/Lotus, Microsoft, Oracle and SAP.
Sounds great. Lots of reasons to go with one of the big vendors (see bullet 2).
How much will it cost? How much will it give back? In other words, can the acquisition be justified with a strong return on investment analysis?
